"These are several parts of the fuselage, engine fragments, various mechanisms and components. All the wreckage is delivered ashore and given to the investigating authorities," the ministry said.
The Russian Defense Ministry's Tu-154 aircraft en route to Syria from Moscow crashed soon after takeoff near Russia's Black Sea resort of Sochi early on Sunday.
The plane was carrying 92 people including eight crew members, 64 musicians of the Alexandrov Ensemble, nine reporters, head of Spravedlivaya Pomoshch (Fair Aid) charity Elizaveta Glinka, and two federal civil servants.
